云数据库上有个集合：class，数据如下：

[

    {

        "name":"一班",

        "students":[

            {

                "studentNo": "101",

                "studentName": "张一"

            }, {

                "studentNo": "102",

                "studentName": "王一"

            }

        ]

    },{

        "name":"二班",

        "students":[

            {

                "studentNo": "201",

                "studentName": "李二"

            }, {

                "studentNo": "202",

                "studentName": "赵二"

            }

        ]

    }

]

我现在有个学号列表，比如["101", "202"]，我想查询class集合，匹配这个学号列表，查询列表中存在的学生，返回的结果中students里只包含匹配的学生信息，也就是说想得到下面的目标数据，请问这个如何实现？

[

    {

        "name":"一班",

        "students":[

            {

                "studentNo": "101",

                "studentName": "张一"

            }

        ]

    },{

        "name":"二班",

        "students":[

            {

                "studentNo": "202",

                "studentName": "赵二"

            }

        ]

    }

]
